Comparative evaluation of deacidification processesMichal Jablonsky
The scope of this paper is the comparative evaluation of the efficacy of deacidification processes mainly in terms of the stability and mechanical permanence of paper during heat induced ageing. The key problem of the mass deacidification comparative evaluation studies performed up till now is large variability of approaches, criteria, methods and experimental conditions used, and lack of international standardisation. We have therefore transformed data from the most important available comparative studies worldwide to a comparable form through estimating sequences, and where possible efficacy factors, or life expectancy extension factors. This method enable a comparison of various aspects of quality and efficacy between two or more deacidification processes and methods of different authors.It enabled to identify the best available technologies (BAT) and formulating recommendations and outlook future research and sustainable development of deacidification. The mass deacidification is a basic technique used by memory institutions wishing to stabilize acid paper documents. It can be used as a dedicated, single purpose technique, however in order to minimise manipulating with the books and costs for repeated logistics, quality and safety controle, it could be a part of an integrated conservation and digitising centre (CDC/ ICDC) or a multifunctional conservation centre (CC).

Synthesis and study of structural and magnetic properties of superparamagneti...Nanomedicine Journal (NMJ)
Objective(s):
This paper describes coating of magnetite nanoparticles (MNPs) with amorphous silica shells.
Materials and Methods:
First, magnetite (Fe3O4) NPs were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. Afterwards, coating with silica was carried out via a sol-gel approach in which the electrostatically stabilized MNPs were used as seeds. The samples were characterized by means of X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy and vibrating sample magnetometer (VSM).
Results:
The results of XRD analysis implied that the prepared nanocomposite consists of two compounds of crystalline magnetite and amorphous silica that formation of their core/shell structure with the shell thickness of about 5 nm was confirmed by TEM images. The magnetic studies also indicated that produced Fe3O4@SiO2 core/shell nanocomposite exhibits superparamagnetic properties at room temperature.
Conclusion:
These core/shell structure due to having superparamagnetic property of Fe3O4 and unique properties of SiO2, offers a high potential for many biomedical applications.

IRJET- Statistical analysis of mechanical properties of Kenaf fiber/ Palmyra ...IRJET Journal
This document describes a study that used Taguchi methods to analyze the mechanical properties of composites made from kenaf fiber, palmyra sprout fiber, and glass fiber reinforced with epoxy resin. Experiments were conducted using a Taguchi L12 orthogonal array to test the effects of fiber weight fraction and fiber type on tensile strength and impact strength. Analysis of variance showed that both fiber weight fraction and fiber type significantly affected the mechanical properties. Regression analysis was used to develop mathematical models relating the properties to the experimental factors. The optimal combination of parameters for strength was found to be 15% weight fraction of kenaf fiber and 7.5% weight fraction of glass fiber.

Degradation of poly-L-lactide. Part 1, IMechE, 2004Dr Neill Weir
The document summarizes a study that evaluated the in vitro and in vivo degradation of poly-L-lactide (PLLA) over time. PLLA samples were processed into rods and tensile specimens, sterilized, and degraded in both physiological buffer solution and implanted subcutaneously in rats. Properties like molecular weight, crystallinity, mechanical strength, and thermal properties were evaluated at various time points. The results showed degradation proceeded at the same rate in both environments, suggesting enzymes did not accelerate degradation in vivo. Additionally, the lack of inflammatory response indicated good biocompatibility of PLLA over the 44-week study period before mass loss was observed.
